Research on Cutting Technology of High-Strength Wear-resistant Steel Plate

High-strength wear-resistant steel plate is an important raw material for military engineering, metallurgical equipment, wear-resistant parts and other industrial fields. It has high wear resistance, high impact toughness, good weldability and workability, and high temperature oxidation resistance. As the application field of high-strength wear-resistant steel plate is larger and larger, the use of high-strength wear-resistant steel plate can be applied in various fields.
    
In the process of cutting high-strength wear-resistant steel plate, the cutting method is suitable for different cutting requirements, such as laser cutting, plasma cutting, flame cutting and waterjet cutting. These cutting processes have different characteristics and limitations.
    
1. Laser cutting
Laser cutting is a cutting method in which a laser beam is applied to the workpiece, and the workpiece is mainly cut by the thermal effect of the laser beam. The laser cutting used in high-strength wear-resistant steel plate involves the vaporization of the metal material, melting, and partial evaporation (explosive effect). The advantages of laser cutting for high-strength wear-resistant steel plate include high cutting accuracy, high cutting speed, good cutting quality and no need for additional processing. The processing cost is high and the heat affected zone is large.
    
2. Plasma cutting
Plasma cutting method is a cutting process that cuts conductive materials by thermally blowing plasma formed by high temperature plasma arc and compressed air. Its cutting speed is fast, and it can be used to cut even thick plates. The requirements for cutting gas are higher than those of laser cutting, and the cutting edge is not as sharp as laser cutting.
    
3. Flame cutting
Flame cutting is mainly used for cutting large sheets, high-strength steel plates and thick steel plates. It uses acetylene and oxygen as the cutting gas. The cutting thickness and cutting speed depend on the cutting gas pressure, oxygen pressure and preheating value. The cutting effect of flame cutting is relatively good, but the preheating time is relatively long and the cutting precision is relatively low.
    
4. Waterjet cutting
Waterjet cutting is a cutting method that uses a jet of highly pressurized water, and the cutting speed is fast and the cutting efficiency is high. However, the cost of waterjet cutting is large and the cutting edge needs to be processed afterwards.
    
In conclusion, the process of cutting high-strength wear-resistant steel plate has various methods, such as laser cutting, plasma cutting, flame cutting and waterjet cutting. Each cutting process has its own advantages and disadvantages. The choice of cutting method depends on the type of steel, its hardness, thickness and size. When cutting, it is important to choose the right cutting method and choose a cutting process that can meet the cutting requirements.
